This Psalm shows the supremacy of Jehovah in all the earth, in all temporal blessings constituted under His hand, therefore forever. It is intimately connected with and dependent on the former Psalm—it is a dependent subject. In the sense of this blessing the Spirit of Christ blesses Jehovah. It involves the consumption of sinners out of the earth.
It appears to me that these Psalms involve the post-millennial blessing—the new heavens and the new earth—and declare its perpetuity, and that it is the time in full when the Son shall be subject, i.e., this time contemplated in joy by the Son, and the hand of Jehovah, which shall produce it, recognized in present government. I say "of all," because the connection of the partial blessing of the millennium is shown to flow from the same faithfulness of Jehovah, the stability of whom, in blessing, is the source from which the Anointed Man, the Head of creation, who in perfect union with Him had tasted the blessing, reckons on, and prophetically (in His own joy, for joy is prophecy, i.e., joy in Jehovah's character, for He is stable) declares the fullness and perpetuity of it. It is therefore a most instructive Psalm, and associates the present existing things with the perpetuity of Jehovah's stability, though man be as grass, yea, may have introduced sin amongst it when given as a portion into his hand. But He, knowing the stability and goodness of Jehovah will sing praise to His "God while he has his being," i.e., it is manifestly the Man, Christ Jesus, in His perpetual life. It is a very wide and blessed Psalm in this reaching out into full and ultimate post-millennial blessing. Its connection with present things is its blessed importance, as marking their blessing and stability in Jehovah, not of course in se, where man is not; see verse 5.
So far as it is Jehovah judging, ruling, in this Psalm it is in Creation, but in the glory of Jehovah, i.e., not simply in Creation as God, as in Psa. 19, where the glory of Creation and the perfection of the Law are abstractedly shown, but as One who, governing and supreme, has His glory (to whom it belongs) as "very great" in the midst of all things—evil being, perhaps, in judgment if needed—but glorified in all, and ministers blessing to man in the midst of this state of things; but "Lord" is His Name with those that fear Him. The young lions, subject to the same power, seek their meat from God. The Spirit of Messiah will praise Him in this, verse 35. There is still a work remaining for Him who, even in the midst of disorder, sees that the earth is the Lord's, and His glory in it (as a righteous Jew should and would), "Let the sinners be consumed out of the earth, and let the wicked be no more." Such is the view of the righteous soul of Messiah in Spirit, viewing the position of Jehovah in the midst of a world whose efforts indeed witnessed misery, but where faith saw Him in the midst of it. "Let sinners be consumed out of the earth, and let the wicked be no more"—such desires are imperious, and for the glory of the Lord, and the desire, providentially, of the children of God, for it is Jehovah Shaddai who calls them His children. But it belongs to the providential government of the world, not to the present position of the children—they are to grow together to the harvest; but by faith, one can have meditations of Him in the providence which precedes it, which are sweet, and most sweet to the soul—it is of a glory which shall endure forever, despite the evil and the efforts of wicked men.
